Portman couldn't make it for the re-shoots after the movie's completion.
Pataky was made to wear a wig and styled to look like Portman's character Dr. Jane Foster in the movie and kiss Hemsworth.
"It was for re-shoots (after the film was finished) and he (Chris) was working in Hong Kong and I couldn't get there because I was working on my own film," Said Portman.
"And so they put his wife in my wig and costume - that's why it was so passionate. It was such a perfect solution, wasn't it," she added.
